Avista Corp. 10-Q Summary: Q3 2025

Business Context and Reporting Period

This report covers the quarterly period ended September 30, 2025. Avista Corporation is a regulated utility holding company operating primarily in the Pacific Northwest (Washington, Idaho, Oregon) and Alaska. Its operations are divided into two main reportable segments: Avista Utilities (regulated electric and natural gas distribution and generation) and Alaska Electric Light and Power Company (AEL&P). The company also maintains non-regulated investments through Avista Capital.

Key Financial Metrics (Nine Months Ended Sept 30, 2025)

Note: Debt-to-capitalization ratio stands at 54.7%, well below the 65% covenant limit.

Material Changes vs. Prior Period

• Revenue Growth: Driven primarily by approved general rate cases in Washington and Idaho, customer growth, and increased load. Electric retail revenue increased $104 million YTD due to rate increases ($64M) and volume growth ($40M).
• Resource Costs: Electric resource costs decreased $59 million YTD due to lower wholesale power prices and increased deferrals of power supply costs under regulatory mechanisms (ERM). Natural gas resource costs decreased $23 million due to lower commodity prices.
• Operating Expenses: Increased due to higher employee salaries/benefits and thermal generation costs. Wildfire mitigation and insurance cost amortizations increased, offset by corresponding revenue increases.
• Investment Losses: The "Other Businesses" segment reported a net loss of $13 million YTD (vs. $3 million loss in 2024), driven by valuation declines in clean technology investments and dilution of ownership percentages.
• Legal Settlements: The company settled the Babb Road Fire litigation for $27 million ($21M paid by Avista), which was fully covered by insurance proceeds, resulting in no net income impact.

Guidance, Outlook, and Risks

• Regulatory Outlook: The company expects to file multi-year general rate cases in Washington and Idaho in Q1 2026. A Colstrip tariff for 2025 is currently subject to refund pending a final order from the Washington Utilities and Transportation Commission (WUTC).
• Capital Plan: Base capital expenditures for Avista Utilities are projected to rise from $525 million in 2025 to $705 million in 2030. The company plans to issue approximately $120 million of long-term debt and up to $80 million of common stock in 2026.
• Resource Needs: An RFP was issued in May 2025 for up to 425 MW of capacity. The company expects hydro generation in 2025 to be approximately 85% of normal, requiring additional thermal generation and market purchases.
• Risks:
  • Regulatory Lag: Delays in rate recovery for inflation and interest rate increases.
  • Wildfire Liability: Ongoing exposure to wildfire litigation and new mitigation legislation in Idaho and Washington.
  • Investment Volatility: Non-utility investments in clean technology remain sensitive to policy changes and market sentiment.
  • ERP Implementation: Risks associated with the multi-year implementation of a new Enterprise Resource Planning system (expected completion 2028).

Investor Verification Checklist

• Verify the final outcome of the Colstrip tariff refund order from the WUTC, as this impacts 2025 revenue recovery.
• Monitor the clean technology investment portfolio valuations, which contributed significantly to the "Other Businesses" segment loss.
• Review the 2026 General Rate Case filings in Q1 2026 to assess future margin recovery.
• Track progress on the ERP system implementation to ensure no material disruption to financial reporting or operations.
• Confirm the status of the Washington Initiative 2066 appeal, which impacts long-term natural gas demand forecasts.
